June 19, 1945, No. 2,398,149, 2,498,699, of Feb. 28, 1950.

The main object of the invention is to provide a spray head of moreeconomical construction than those heretofore used and one of universalapplication in that the same spray head structure can be used whetherthe water supply comes from below or above the wash basin into which thespray head discharges. More particularly, instead of a large brasscasting forming one of the parts of the usual spray head in which themanifold is integral with a spraying part, the manifold is now made as areversible single smaller casting and the spray head parts are formed ofstainless steel stampings clamped to the manifold in elther of itspositions, the stampings being cheaper than the brass parts previouslyused and better than the plated brass surfaces of the parts previouslyused.

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. l is a vertical sectional view through a wash fountain equippedwitha spray head embodying the invention;

Fig. 2 is a vertical sectional view of a spray head as arranged toreceive water from a point below the wash basin;

Fig. 3 is a view similar to Fig. 2 showing the spray head as arranged toreceive water from a point above the spray head;

Fig. 4 is a top View of the manifold as arranged in Fig. 3.

Referring to Figs. 2 to 4, the spray head embodying the inventioncomprises a manifold 5 and spray nozzle parts 6 and 7. The manifold 5 isa generally cylindrical member having annular grooves 8 and 9 adjacentits ends and associated grooves 10 and 11. The external grooves 8 and 9are of the same inner diameter, and the internal grooves 10 and 11 havethe same outer diameter. The manifold is usually formed as a brasscasting and is of generally ring shape or annular form with an inwardlyprojecting boss 12 apertured at one side a-t 13 to provide a taperedopening for a water supply pipe 15.

The nozzle member 6 is an annular plate stamping of stainless steelhaving a depending ange portion 16 whose edge 17 may be bevelled. Thisstamping has radially disposed circumferentially spaced tubularinternally threaded bosses 18 welded thereto. The nozzle member 17 isalso an annular plate stamping of stainless steel having a flange 19with an upper bevelled edge 20 that ts the bevelled edge 17 of thenozzle member 6. Either one or both of these nozzle members where theyabut each other at their bevelled edges 17 and 20 may be provided withgrooves 21 forming spray openings. These grooves are circumferentiallyspaced from each other, and for a full circle wash fountain the groovesare ar- Patented Oct. 9, 195,6

ranged throughout the entire area of the nozzle,whereas for asemi-circular wash fountain such as shown in Figs. 7 and 8 of PatentkNo.2,378,424, previously referred to, the` spray openings are formed onlyin the front half portion of the spray head.

The nozzle members 6 and 7 are clamped to each other in spray formingposition and to the manifold 5 by st ud i on these studs and bearingagainst fiber washers 24 which abut recessed portions 25 of the nozzlemember 7 to secure a fluid-tight connection water proof materialaremounted in the recesses `8 and 9 of the manifold and engage the innerperipheral portions of the spray members 6 and 7.

The opening 13 for the pipe 15 opens into the space between the nozzlemembers 6 and end of the pipe cross bar 30, and nut 31 engaging thelower threaded end of the tie bar 29. The tie bar 29 ex-tends through anopening 32 in a cover plate 33. Cover plate 33 has the same outerdiameter as that of the support 28, and these diameters are such as totit either the internal groove 10 or 11.

In Fig. 3 the nozzle member is supported by the same type of tubularsupport 28 as previously described but is held to this support by theconnection of a cover plate 33a -through a set screw 34 engaging a ventpipe 35, and in this form it will be noted that the manifold 5 has beenturned over from the position shown in Fig. 2 so that the water supplypipe 15 comes in from the top instead of the bot-tom. Various types ofvalves some of which are shown in the prior patents above referred tomay be used to control the supply of water to the pipe 15.

I desire it to be understood that this invention is not to be limited toany particular form or arrangement of parts except in so far as suchlimitations are included in the claims.

What I claim as my invention is:

1. In a wash fountain spray head, lthe combination of a cast metalmanifold of tubular form having an inwardly extending eccentricallydisposed boss provided with a single water inlet and having concentricexternal centering means at its ends, a pair of stamped metal annularnozzle members having edge engaging spray forming outer peripheral angesand having inner peripheral portions engageable with either of saidcentering means of said manifold, sealing means between the innerperipheries of the nozzle members and said manifold, and

means for clamping said nozzle members together and to said manifold,said manifold being reversible relative to said nozzle members wherebysaid water inlet may be disposed at the top or bottom of said sprayhead.

2. In a washfountain spray head, the combination of a cast metalmanifold of tubular form having an inwardly extending eccentricallydisposed boss provided with a single water inlet and annular peripheralconcentric recesses of the same internal diameter adjacent its ends, apair of annular metal plate stampings forming nozzle members having edgeengaging spray forming peripheral anges and having inner peripheralportions fitting either of said peripheral recesses of said manifold,sealing rings disposed in said recess and engaged by said nozzlemembers, and means for clamping said nozzle members together and to saidmanifold, said manifold being reversible members whereby said waterinlet bottom or said spray head. head, the combination of relative tosaid nozzle may be disposed at `the top or 3. In a Washfountain spray acast metal tubular manifold having external concentrically disposedgrooves of the same internal diameter at opposite end portions thereofand internal concentric grooves of the same external diameter atopposite ends thereof, said manifold having an inwardly extendingeccentrically disposed boss provided with a single water inlet, a pairof annular stainless steel plate stampings having edge engaging sprayforming peripheral iianges and having inner peripheral portions of thesame diameter to engage in either of said external grooves of saidmanifold, sealing means between the inner peripheries of said plates andsaid manifold, one of said plates `having inwardly extending threadedbosses, bolts extending through the other of said plates and engaging insaid threaded bosses to clamp said plate members together and to saidmanifold, sealing means interposed between the heads of said bolts andthe adjacent plate, `a tubular support and a circular cover memberhaving ythe same external diameter as said support, said support andcover member adapted to engage in either of said internal grooves ofsaid manifold whereby said manifold may be reversed relative to saidplates, said support and said cover member to dispose said water inletat the top or bottom of said spray head.
